+# AWS Lambda + Layer Load Test

+## Links
+
+https://www.ibm.com/docs/en/instana-observability/current?topic=lambda-aws-native-tracing-nodejs#architecture-x8664
+
+## Deploy released & test
+
+This is helpful to test against the released behavior.
+Uses the released layer, creates the zip and deploys the fn.
+
+```sh
+RELEASED=1 INSTANA_ENDPOINT_URL=... INSTANA_AGENT_KEY=... REGION=us-east-1 ./load-test/deploy.sh
+RELEASED=1 node ./load-test/test.js
+./load-test/cleanup.sh
+```
+
+## Deploy local & test
+
+Publishes the local experimental lambda layer, creates the zip and deploys the fn.
+
+```sh
+INSTANA_ENDPOINT_URL=... INSTANA_AGENT_KEY=... REGION=us-east-1 ./load-test/deploy.sh
+node ./load-test/test.js
+./load-test/cleanup.sh
